Updates

  • (Edwin) Trace tree update - rebuilding pipeline state and cost of recompilation. Now handles merge notes. Optimizing it now off of previous branches. Constant recompiling is more than expected, so will continue to investigate.
    • Can turn trace trees on and it will pass the tests, but the performance is worse, so currently are leaving it off.
    • Pipelining is now starting to pay off!
  • (Andreas) Compartmentalizing nanojit for use by tracemonkey as well as TT
    • It was a small namespace change. Add a delete operator?
    • Should we start a wiki page to track these items? Or Bugzilla? ACTION: Andreas will write something up and send out a link.
    • Moving more filters (e.g., CSE) into nanojit
  • (Mark) Wondering about ASC on TT.
    • ACTION: Dan will touch base with Mark on this to assist.
